Re: BUG: Mailbox renaming algorithm got into a potentially infinite loop, aborting

You could try fix this by manually renaming the problematic folder. This is a bug though.

Hi all! I'm using Dovecot 2.2.36.4. Maybe someone can help, this bug makes the replication unusable for me.

Thanks, Alex

Hi all!

I have two dovecot servers with dsync replication over tcp.
Replication works fine except for one user.

# doveadm replicator status
username                                                                                                
priority fast sync full sync success sync failed
customer@example.com
<mailto:customer@example.com>                                                                           
none     00:00:33  07:03:23  03:22:31     y

If i run dsync manually, i get the following error message:

dsync-local(customer@example.com <mailto:customer@example.com>):
Debug: brain M: -- Mailbox renamed, restart sync --
dsync-local(customer@example.com <mailto:customer@example.com>):
Error: BUG: Mailbox renaming algorithm got into a potentially

dsync-local(customer@example.com <mailto:customer@example.com>):
Error: Mailbox INBOX.Foldername sync: mailbox_rename failed:

For more info see the attached sync_loop.log

Thanks for your help,
